The team-up between British art-rock geniuses and halftime-show entertainment was a particularly unlikely one, but it managed to overshadow everything else that happened at the Grammys this year, with the possible exception of a very pregnant M.I.A. rocking the stage in a ladybug dress.

Months later, this version of "15 Step" has finally seen commercial release, of a sort. The Trojan Marching Band has released a double-CD called Trojan Legacy, available only at the USC Bookstore and the Bookstore's website. It includes a recording of "15 Step" taped at a rehearsal two days before the Grammys, as well as marching band versions of many popular songs. This gives all of us the rare opportunity to hear Thom Yorke on the same album as two Breaking Benjamin covers.
